NCF has multiple filtering processes in place to weed out spam email. Despite best efforts, some spam messages will reach you over time.
If there is something about the nature of the spam messages that warrants it or if you don't know what to do with them or you're not sure if they are SPAM, feel free to contact to the HelpDesk at email@example.com or 613.721.1773 x0.
